ExactSpelling:=False, CharSet:=CharSet.Auto, SetLastError:=True)> _
Public Function EnumWindowStations(ByVal lpEnumFunc As EnumWindowStationsDelegate, ByVal lParam As IntPtr) As Boolean
        ' Leave function empty - DLLImport attribute forwards calls
    End Function

!!!!User-Defined Types:

!!!!Sample Code:
{   
    class Program
    {
        [DllImport( "user32.dll" )]
        private static extern bool EnumWindowStations( EnumWindowStationsDelegate lpEnumFunc, IntPtr lParam );

private delegate bool EnumWindowStationsDelegate( string windowsStation, IntPtr lParam );

private static bool EnumWindowStationsCallback( string windowStation, IntPtr lParam )
        {
            GCHandle gch       = GCHandle.FromIntPtr( lParam );
            IList<string> list = gch.Target as List<string>;

if ( null == list ) {
                return (false);
            }

list.Add( windowStation );

return (true);
        }

static void Main()
        {
            IList<string> list                   = new List<string>();
            GCHandle gch                         = GCHandle.Alloc( list );
            EnumWindowStationsDelegate childProc = new EnumWindowStationsDelegate( EnumWindowStationsCallback );

EnumWindowStations( childProc, GCHandle.ToIntPtr( gch ) );

foreach ( string a in list ) {
                Console.WriteLine( a );
            }

Console.ReadKey();
        }
    }
